A small wire soldered to the larger bearing tube and then to the frog rail gives excellent electrical connection from point to frog. My first switch machine was also purchased, but apparently I bought the wrong kind, for then and there I decided to build my own machines. 1... 0.1 -**: ( 40 641 lifted out for servicing or cleaning and '6,4.. ·· .., ell ..., ..IL•.':.'..'< •I:.--8.2= ':.t, L.9'1. : * .- 03617 replaced within seconds.

They work very well but I am anxious to try friction drive, for I believe that it ' has at least one distinct advantage. The signaling system, at present, is far from complete. My operating semaphores are impulse-operated bymeans of insulated track sections, and very few signal lights are relay operated. For the most part, however, I tell where the trains are by looking and also by listening, for I have about 30 ft. of tunnels and even one turnout in a tunnel. The control panel is at present laid out for one-man operation but will be changed to cab control shortly for the convenience of my son and me. All turnouts are indicated on the panel and the system is laid out in 12 blocks. Of course, our railroad is not complete-and I hope that it never will be. Having found the best hobby in the world, I want to work at it for many years to come. 27 bulbs. Another wire was run from the bulbs continuously without loss of brilliance, no matter how many are -
